Product overview

Delivery

Corsair RM Series power supplies are fully modular and optimized for silence and high efficiency. Zero RPM Fan Mode means that the fan doesn't even spin until the power supply is under heavy load, and the fan is custom-designed for low noise operation even at high loads. 80 PLUS Gold rated efficiency saves you money on your power bill, and the flat black cables are fully modular, so you can enjoy fast, neat builds. And, like all Corsair power supplies, RM Series is built with high-quality components and is guaranteed to deliver clean, stable, continuous power. Connect it to your Corsair Link system and you can even monitor fan speed and +12V current directly from your desktop (additional cable required for 450W-850W units).

Optimized for Silence

The efficient design of the RM Series means minimal excess heat generation, and thanks to the Zero RPM fan mode the fan doesn't even need to spin under low to medium loads. The custom-designed fan has an optimized blade profile for low-turbulence airflow and near-silent operation even at full speed. And when you're pushing it hard, the thermal sensor controls the fan speed to ensure that it gets the cooling it needs without any extra noise.

The components used to manufacture the RM Series are manufactured specifically for excellent performance and low audible noise.

80 PLUS Gold-certified Efficiency

Highly efficient RM Series power supplies produce less heat and have lower operating costs.

Flat black, Low-Profile Modular Cables

You can use only the cables you need, and leave the rest in the box for fast, easy, and great-looking builds.

Reliable, Continuous Power Delivery

RM Series power ratings are continuous, not peak, for superior protection for your valuable PC. Corsair uses high-quality internal components, and RM Series power supplies are guaranteed to deliver clean, stable, continuous power.

Corsair Link Compatible

Want even more? RM Series power supplies connect to Corsair Link software for real-time monitoring of fan speed and power delivery directly from your desktop. Additional hardware required for 450W-850W units. See corsair.com for more details.

bought it with the Intel Core i7 4770K bundle really very quiet. Cannot fault it. Moidular system makes it really easy to wire in as only use the plugs you need. Would buy again if need to

Very good power supply

This PSU was very easy to install in my case. Though it must be noted that it is quite long, as it is modular.

When I was testing my parts outside of the case to make sure everything functioned, I found that the 24 pin connector was very difficult to unplug from my motherboard. HOWEVER, I am not sure if this was a problem with my cables, or my socket.

The modularity of the PSU means that my cable management was very easy to do, and so my case looks very tidy compared to what it would look like with a non-modular PSU.

I also appreciate the possibility of using Corsair Link to monitor the temperature of my PSU, and that the fan is stopped at lower temperatures making it completely silent.

Disappointed - Dead after 9 days

Very disappointed to report that this PSU went dead after 9 days use. I powered it off while away for a weekend, and it failed to power up again since. All checks state a faulty PSU. IF this were not bad enough, BT are not contactable and the website simply points me to the manufacturer! THIS IS NOT GOOD ENOUGH! Corsair are almost impossible to reach, the RMA reporting is complex and a week after contacting them, I still have no response. When buying ANYTHING like this, I urge you to check the returns policy of the vendor and how easy it is to contact them. BT has washed their hands of me as there is no way to use their RMA process.
